Inventor: AIMONO TOSHIAKI
IPC: B62M1/32
Filed: 2020-07-08
Abstract: To provide a mechanism that does not need a large force to start at the time of traveling or to depress a pedal on a bad road or slope.SOLUTION: A mechanism that addresses a shortage of a traveling force uses an elongated crank, which is five times longer than that of an existing bicycle, to transmit a rotation torque, which is approximately five times larger, to a rear wheel via a one-way clutch. Left and right pedals are alternately straight depressed, and the elongated crank fixed to a specified position on a guide belt hung on a guide pully of a guide mechanism is repetitively reciprocated and slid to a slide position. A torque generation dead zone near an upper or lower dead point of crank rotation and a component force at a crank rotation angle are reduced as much as possible. A pedal depression force can be transmitted as an effective torque to the rear wheel drive side.SELECTED DRAWING: Figure 1
